answ2. Many get by with an exoskeleton, such as insects.
And butterflies and bees fly without a rigid exoskeleton.
Animals in the water have no trouble, such as octopuses and worms.
They get by by flying, swimming, or moving articulated legs.
They move with their leg muscles. The muscles take electrical impulses from the brain, and then either expand or contract to move the ligaments and bones.
Not all species in the kingdom Animalia are able to move. Of the species that can move, they use their legs/feet to walk or shuffle their bodies along the ground.
Animals with exoskeletons have tow or more pieces that move the parts by means of muscles. The muscles attach to the inner surface.
